Screening of the essential oil composition of wild Sicilian thyme

Influence of harvesting time on composition of the essential oil of Thymus capitatus (L.) Hoffmanns. & Link. growing wild in northern Sicily and its activity on microorganisms affecting historical art crafts

“…Our results on Tc2 and Tc3, when compared with the data reported in the literature for the oil of T. capitatus collected in the southern part of Sicily (Napoli et al, 2010), indicate a similar profile. In fact, the range of carvacrol (70-83%), cterpinene (t-10%) and p-cymene (4-8%) is similar to those of Tc2 and Tc3.…”

“…Several papers have been published on the chemical composition of the essential oil of T. capitatus (Cosentino et al, 1999;Arras and Usai, 2001;Miceli et al, 2006;El Ajjouri et al, 2008;Figueiredo et al, 2008;Blanco et al, 2010;Napoli et al, 2010;Tawaha and Hudaib, 2012;Yvon et al, 2012;BallesterCosta et al, 2013;Chedia et al, 2013;Saoud et al, 2013;Hortigo´n-Vinagre et al, 2014;Bouayad Alam et al, 2014). It is very rich in the terpenes thymol, carvacrol, and p-cymene.…”

Antimicrobial activity of Thymus longicaulis C. Presl essential oil against respiratory pathogens

“…These results, obtained for the plant sample originating from the Central Dalmatia region of Croatia, are in partial agreement with previously reported data on T. longicaulis collected in the other Croatian geographic region (Istria) in which thymol and p-cymene were the predominant components [19]. On the other hand, our findings differ from previous data on the essential oil of T. longicaulis from Serbia and Italy which demonstrated α-terpinyl acetate [24], p-cymene [25] and geraniol [28] as the main components of these oils. Antibacterial and antifungal activities of the essential oil isolated from T. longicaulis against pathogens of the respiratory tract were assessed according to the inhibition zones (ZI) as well as values of minimum inhibitory concentrations (MIC) and the results are presented in Table 2.…”

“…It is a traditional remedy for cold, flu, cough, nephritis and abdominal pain [15][16][17][18]. To the best of our knowledge, there are several reports on the essential oil analysis of different taxa of T. longicaulis, and the results revealed their marked chemical variations depending on genetically determined properties, localities and environmental factors [19][20][21][22][23][24][25][26]. Three reports have been published concerning the antimicrobial activity of T. longicaulis recently.…”

Chemical characterization and antibacterial activity of Thymus moroderi and Thymus piperella essential oils, two Thymus endemic species from southeast of Spain

“…In another study the same authors (Bagamboula, Uyttendaele, & Debevere, 2004) investigated the EO of thyme, identifying 28 compounds, which represented 92.6% of the total oil, the major constituents being thymol (32.23%), g-terpinene (21.19%) and para-cymene (20.27%). Napoli, Curcuruto, and Ruberto (2010) reported on the composition of the essential oils of the thirty samples of thyme collected in Italy. In total, 46 components were fully identified, covering more than 96% of the total composition.…”
